RUG-BEATING MACHINE.

Application filed October ,4. 1923. Serial fNo.-'666,445.

chine fori'the purpose stated which is self- =contained and in which the parts are arrangedwithin the compass of a relatively small-casing which may be readily transported to the. desired place of operation.

Numerous other objects and ad vantage? of the inventionwill be'aipparent as it is better understood from the following description, whiclntaken'in connection-with the accomcasing. Bnaces '32hextendjfrom the outer 1 ends of the bar 27 and are connected tothe upper endsof the uprights 28, therebeing .said uprights and connected :thereto at, the point of attachment of the-braces 32.

Said-motor is supported by. brackets 4.1-secured to said cross connectors'29. A motor shaft 42 carriesat its outer end a small pulley 43,

l which is adapted to-drive a belt 44 taking {tallying drawings, discloses a preferred em- "b'odiment thereofl Referring to th'edrawlngs,

' Fig. 2 is an end view, also partially-broken awayy 3 is an enlarged detail view of the spider, showing the means by which the straps are secured thereto;

Fig. 4' is a partial longitudinal section of said spider;

Fig. 5 is a still further enlarged partial .plan view 'of the strap holding bar; and

Fig. 6 is a sectional view of said bar bent to the form in which it is used. The machine which I have shown on the drawings. for purposes of illustration, comprises a casing 21 which is formed of sheet metal or the like and which is supported by rear wheels 22 and a steering wheel 23, a handle 24 being provided at the front of said casing and the operating parts being disposed within the casing, as will hereinafter appear.

The wheels 22 are supported upon short shafts 25, which extend through the casing and having bearings in brackets 26 depend ing from longitudinal frame bars 27 secured within said casing at the opposite sides thereof. Uprights 28 are secured to the frame bars 27 and support cross connectors 29 at the top of a sloping portion 31 of the over a largepulley carried on a transverse-shaft 46 upon whichthe .rug beating mechanism is mounted. An idler wheel 47 is mounted in arms 48 pivoted'at 49 to one of 'the uprights 28 and is held in contact with the .belt. 44to providethe desired tension thereonby-meansof a spring 51 secured at one end to an arm 48 and at the opposite end to an opposite upright 28.

The rug beating mechanism comprises a plurality of beater straps 52 secured to spiders 53, which are in turn secured to the opposite ends of the shaft 46 by means of pins 54, and side plates 55 extending between adjacent arms of said spider and being preferably formed of sheet metal, or other'like material. A plate 56 is provided for each corner of the frame and is bent to a U-"shape, as shown in Figure 6. Said plate is perfo rated, as indicated at 57, and is adapted to be held in place by means of bolts 58 extending through the edges 59 of the plates 55 and through the ends of the spider arms, as clearly shown in Fig. 3. The plates 56 are provided with spaced series of slots 61 which are disposed at the bend when said plates are in position. Rods 62 are adapted to extend through the U-plates beyond the ends of the spider arms, and laces 63 are employed to bind the straps 52 onto said rods 62, it being obvious that said straps may extend through the slots 61 in the plate 56. In this manner, the straps 52 are firmly secured to the drum and it will be obvious that, upon rotation of the latter, said straps areeaused tostrike' a rug-upon which the machine may be positioned. Said, straps, while preferably.,relatively heavy and of sufiicientstitlness' to cause themnto be nor-.1

mally projected, as shown in Fig. 1, are bent by contact with the rug, as clearly illustrated at the bottom of said figure. The straps, at the different corners of the drum, a1'e--ar-. ranged in staggered relationship and when said drum is driven by the motor 39, the

entire width of the rugbetween the ends of the drum is'subjected to a violent beating action which wnl cause the dust and (hit N.

to be freed in the weil-known manner, afan 64 being provided on the motor shaftand adapted to-draw the dirt through an opening'65 and into a receptacle 66 of any preferred form, positioned in the end of the upper casing 38.

-The machine may be readily transported from one position to -an0ther,so that the entire rug surface may be subjected to beating and also in order that the machine may be moved-from place to place. '24 is disposed at a convenient height so that the machine may b'e'pushe'd or drawn, as

The handle dcsired, the steering wheel 23 being disposed in advance of the casing 21 and being movable about a vert1cal ax1s PIOVldQCl by a bearing 67 secured to the outer end of 'frame'bracket- 68; Said wheel is held in a yoke 69 provided with an upwardly extending stud 71 adapted to fit within a socket in the bearing member 67 after the fashion of a caster.

the bars or plates 27, 2S and 29.

The described mechanism obviously performs its function in wholly automatic manner and with rapidity and eflicicncy which is not possible with the usual methods employed. The machine may be used in cleaning establishments,

or may be readily adapted for individual use. as desired.

It is thought thatthe invention and many of its attendant advantages will be understood from the foregoing description. and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention, or

The plates and the two spiders 53 form a drum, mounted for rotation in the frame composed 1n part of' sacrificing all of its material advantages,

the form-hereinbefore described being merely a preferred embodiment thereof.
